Lub khw yog cov khoom siv tshiab niaj hnub no. Yuav ua li cas xaiv qhov zoo tshaj plaws rwb thaiv tshooj rau lub sam thiaj tsis ua ib qho yuam kev uas yuav lwj cov txiaj ntsim ntawm kim kho vaj tse? Peb muab ntawm no ib daim ntawv teev cov nrov heaters, nrog kev piav qhia ntawm lawv cov ntsiab lus tseem ceeb.
Cov rwb thaiv tsev twg thiaj zoo dua rau lub sam thiaj?
- Penofol . Cov khoom siv no tau muab tso rau hauv qaws. Nyob ntawm hom, cov ntawv ci yuav ua tau rau ib sab, ob sab, los yog ntawm ib sab lub ntawv ci, thiab nyob rau ob - ib qho nplaum. Nyob rau hauv ib cheeb tsam txias heev, nws yog qhov zoo uas siv cov penoplex ua thawj txheej, thiab penofol ua ob txheej. Thaum teem cov rwb thaiv tsev rau lub sam thiaj yog yooj yim heev.
- Penoplex . Cov khoom no feem ntau siv nyob rau hauv daim ntawv ntawm rwb thaiv tsev rau hauv pem teb thiab phab ntsa ntawm lub sam thiaj. Lub coefficient ntawm thermal conductivity ntawm nws nyob rau qhov siab (0.03 W / (m * K)). Me me feem pua ntawm cov dej nqus dej. 3 cm ntawm penopolix ntau xyoo 10 cm txheej ntawm npaus. Nyob rau hauv kev ua haujlwm, nws yog zoo tagnrho, mob nyuab siab, yuav txiav tau yooj yim thiab tsis crumble.
- Polyurethane ua npuas ncauj . Cov cuab yeej ntawm kev sib tsoo ntawm kev sib tshuam los ntawm kev txau ntawm polyurethane ua npuas dej muaj ntau tus nqi zoo, tab sis yuav tsum muaj kev tshwj xeeb kev txhim kho. Qhov coefficient ntawm thermal conductivity ntawm no tshuaj yog heev siab, nyob rau hauv kev xyaum nws yog tus thawj coj ntawm xws li cov ntaub ntawv. Tsis tas li ntawd xwb, koj yuav tsum ua kom tag nrho cov microcracks thiab pores uas tsis pom qhov muag. Qhov no rwb thaiv kev rau phab ntsa ntawm lub sam thiaj yuav nrog ib qho ntawm tus so ntawm qhov chaw.
- Polyfoam . Ntawm qhov zoo ntawm polystyrene nyob rau hauv thawj qhov chaw - feem ntau nqis nqi. Ua hauj lwm rau qhov rwb thaiv tsev rau lub sam thiaj hauv mus rau 50 xyoo, thiab ua hauj lwm nrog nws tsuas yog. Lub thermal conductivity ntawm cov khoom no yog ib txwm (txog 0.044 W / (m * K)). Txawm hais tias tus npuas yas ua rau nws kub, nws kub taws kub heev - 491 °. Ib tug me me qhov teeb meem uas cuam tshuam nrog rau kev ua hauj lwm - cov khoom no crumbles.
- Cov ntxhuav dawb . Nyob rau hauv cov nqe lus nug ntawm xaiv ib lub rhaub rau ib lub sam thiaj, ib tug tsis ignore xws nrov khoom raws li pob zeb hauv av ntaub plaub. Nws tshwm sim nyob rau hauv daim ntawv ntawm daim hlau los yog nyob rau hauv qaws. Cov thermal conductivity ntawm no yog nyob rau hauv (0.045-0.07), thiab qhov nqus dej noo yog 0.5%. Qhov zoo ntawm cov ntxhia pob zeb yog cov khoom uas tsis yog ua kom siv tau hluav taws xob uas tuaj yeem muab suab nrov zoo nkauj. Haum rau cov qauv uas cov khoom thaiv rwb tsis muaj loads. Rau tus nqi, nws yog nyob rau hauv nruab nrab ntawm daim ntawv.
Cov ntxhuav daig yog tuab thiab yuav tsum tau siv lub installation, tab sis nws tsis hlawv thiab yog ib qho zoo suab nrov insulator. Polyfoam yog pheej yig, tab sis ua tsis tau zoo rau tus so ntawm tus tsis convex. Nrog npaus nws yog nyuaj ua hauj lwm, nws yuav tsum tau kev txawj ntse thiab ib tug tshwj xeeb lub cuab tam, tab sis nws muaj cov yam ntxwv zoo. Feem ntau nws yog ib qho tsim nyog los ua ke ntau cov ntaub ntawv rau ib tug zoo dua cov nyhuv. Yog li, qhov zoo tshaj plaws thaiv kev rau lub sam thiaj yuav tsum tau xaiv raws koj pob nyiaj, qhov loj ntawm lub sam thiaj, thiab tseem ua los ntawm qhov siab tshaj plaws uas koj xav ua kom tiav kev ua haujlwm.
